MPLS / VPLS / ALPHABET SOUP
- MPLS
- VPLS
- WHY AND WHEN?
SLIDE 5
WHY SHOULD I EVEN CARE ABOUT MPLS?
- SCALABILITY
- TRAFFIC ENGINEERING
- QOS
- REDUNDANCY
- INDEPENDENT OF LAYER 2 AND LAYER 3 PROTOCOLS
- BUT I CAN DO THIS WITH OSPF AND BGP ALREADY?
SLIDE 6
SLIDE 7
MPLS…
- MPLS IS LAYER 2.5
- YOU STILL NEED THINGS LIKE OSPF, BGP
, EIGRP FOR IP
- IF YOU ARE RUNNING RIP COME SEE ME. YOU NEED HELP. I WILL HELP
YOU FOR FREE YOU POOR B@$%!RD.

- IF YOU ARE RUNNING STATIC ROUTES COMFORTABLY YOU PROBABLY
DON’T HAVE A NEED FOR MPLS
SLIDE 8
DRAWBACKS TO MPLS
- MORE ADMINISTRATIVE OVERHEAD
- LARGER MTUS NEEDED
- INCREASED NETWORK COMPLEXITY
- CHANGE IS SCARY
- DO I REALLY NEED MPLS?
SLIDE 9
MPLS SECURITY
- EASY TO SPOOF IP ADDRESSES, ALMOST IMPOSSIBLE TO SPOOF
LABELS
- EVERY PE ROUTER MAINTAINS A SEPARATE BRF
- DOES NOT DO ENCRYPTION OR AUTHENTICATION
- MOST ATTACKS ARE AGAINST THE PE ROUTER OR THE ROUTING
ON TOP OF MPLS
SLIDE 10
VPLS
- VPLS CAN HELP YOU SAVE IP ADDRESSES
- TUNNEL BACK TO A CENTRAL CORE WHERE A SINGLE POOL
CAN ASSIGN IPS
- WILL EOIP DO THE SAME FOR ME?
SLIDE 11
NETWORK PHILOSOPHY
SLIDE 12
WHERE TO USE?
SLIDE 13
SWITCH CENTRIC
- Switch Fabric from 2013
- Transport and Transit circuits terminated
- n Cisco Chassis (pre mikrotik switching)
- Routers in VRRP
- BGP routers fed into VRRP Core
- Switches Switch Routers Route
SLIDE 14
SMALL SWITCH CENTRIC
